Really? I read it as a counter to my point... saying that if they want to actually fit the pregnancy fetish, they need to have more Tanya scenes, regardless of her status as an optional LI.
But I've been known to misread things, so if I did so, I apologize. Regardless, I'm trying to take a rational, resources-driven approach, while acknowledging that there are valid reasons for people to want more of Tanya from a story perspective.
Edit: I think I agree with people that if Tanya was going to be added as a pregnant character and then the mother of your first (potentially two) children, it would have made more sense to NOT have her be optional, and then avoid the whole resources dilemma. Like FG, I would prefer to have otherwise just noped her out of the storyline rather than have her be a non-existent presence in the basement, even if I don't expect any more because of her status as an optional LI.
